Defensive publication

ABSTRACT

LIQUID COATING COMPOSITION COMPRISING A CELLULOSE ESTER OF AT LEAST ONE MONOCARBOXYLIC ACID HAVING 2 TO 4 CARBON ATOMS, A UREA FORMALDEHYDE OR MELAMINE COMPOUND, A SILICONE COMPOUND AND ACID CATALYST IS DISCLOSED. THIS COMPOSITION IS APPLIED IN SOLUTION AND IS THERMOSETTING. WHEN CURED, IT PROVIDES A RELEASE COATING WHICH ALSO IMPARTS SCUFF RESISTANCE, HEAT RESISTANCE, WATER RESISTANCE AND CHEMICAL RESISTANCE TO THE COATED SUBSTRATE. THE CELLULOSE ESTER AND UREA FORMALDEHYDE ARE PRESENT IN MAJOR PROPORTIONS, WHILE THE SILICON COMPOUND AND ACID CATALYST ARE PRESENT IN MINOR QUANTITIES.

Filed Sept. 1, 1972, Ser. No. 285,788 Int. Cl. C08b 21/08 U.S. Cl. 26015 No Drawing. 6 Pages Specification Liquid coating composition comprising a cellulose ester of at least one monocarboxylic acid having 2 to 4 carbon atoms, a urea formaldehyde or melamine compound, a silicone compound and acid catalyst is disclosed. This composition is applied in solution and is thermosetting. When cured, it provides a release coating which also imparts scufi? resistance, heat resistance, water resistance and chemical resistance to the coated substrate. The cellulose ester and urea formaldehyde are present in major proportions, while the silicone compound and acid catalyst are present in minor quantities.
